Midori Kanda is cosplaying as Matako Kijima from 3-Nen Z-Gumi GinPachi-sensei. Matako Kijima (来島また子 Kijima Matako), known as the Red Bullet (紅い弾丸 Akai Dangan), is the only female member of the Kiheitai and is skilled in using a pair of revolvers. She is fiercely loyal to Takasugi. She is quick-tempered and prone to screeching when she's upset. This is evident when she has a "spitting fight" with Kagura after she spat at her and when she starts yelling at Kagura after her underwear is said to be stained. She interacts the most with Takechi, the schemer of the Kihetai, calling him "senpai" out of respect, but also calling him a "pervert" and a "lolicon" for sparing Kagura instead of killing her. In chapter 294 of the manga, she, Takechi, and Bansai send Gin a New Years card in order to receive more screen time. She is voiced by Risa Hayamizu.
